Cooling the earth

As the world continues to struggle with climate change and its effects, sustainable development has become a critical topic. As seen in the presentation from Professor Phillip Trotter the 24.04.2023 at ETHZ cooling is an essential aspect of sustainable development as it enables us to maintain comfortable living even in areas where the climate change will causes severe heatwaves.


Also working conditions while minimizing energy consumption and greenhouse gas emissions by minimizing food waste through efficient cold storage supply chains. In this blog post, we will explore the importance of cooling for sustainable development and the steps we can take to ensure that we achieve it.


Importance of Cooling for Sustainable Development

Cooling is essential for sustainable development for several reasons. First, it enables us to maintain comfortable living and working conditions, which are critical for human health, productivity, and well-being. Extreme heat can cause heat stress, dehydration, and other health problems, making it difficult for people to work, study, and carry out their daily activities. With adequate cooling, people can remain comfortable and healthy, thereby improving their productivity and quality of life.


Second, cooling is essential for various industries, such as food, data centers and medicine production, storage as seen in the corona pandemic. These industries require temperature-controlled environments to maintain product quality and prevent spoilage. Without adequate cooling, food and medicine can spoil, resulting in significant economic losses and food waste. In data centers energy suppliers, high temperatures can cause equipment failures, resulting in data loss and downtime in the energy supply.


However, traditional cooling systems, such as air conditioning, refrigerators, and ventilation, consume a significant amount of energy and emit greenhouse gases. These emissions contribute to climate change and its adverse effects, such as sea-level rise, extreme weather events which can cause food insecurity. Therefore, to achieve sustainable development, we need to adopt cooling solutions that minimize energy consumption and greenhouse gas emissions by developing more green energy and better cold storage supply chains.


A few steps to Achieve Cooling for Sustainable Development

There are several steps we can take to achieve cooling for sustainable development. These include:

  1. Energy-Efficient Cooling Systems and buildings: Energy-efficient cooling systems are designed to minimize energy consumption and greenhouse gas emissions while maintaining comfortable indoor conditions. These systems include passive cooling, such as using outdoor passive coolers like vegetation, insulation, and ventilation, and active cooling, such as efficient air conditioning and refrigeration systems. These systems use renewable energy sources, such as solar and wind, to power cooling equipment, further reducing their environmental impact.
  2. Education and Awareness: Education and awareness are critical for achieving cooling for sustainable development. The public needs to understand the importance of energy-efficient cooling systems and their environmental impact. Governments and organizations can provide education and training programs to promote the adoption of sustainable cooling solutions and not to use them if not necessary.
  3. Efficient cold storage supply chains can have a significant impact on improving living conditions in Africa. By reducing food waste and increasing food safety, cold storage facilities can provide farmers with access to new markets and opportunities to increase their income because they will have more time to make better deals and not to fear they product is going bad. This can contribute to economic growth and poverty reduction, while also improving food security and reducing hunger. Cold storage supply chains can play a crucial role in improving the livelihoods of people in Africa and creating a sustainable future for the continent. But not only in Africa also western countries like the USA or China have to improve their supply chains to minimize food waste.



Cooling is essential for sustainable development, as it enables us to maintain comfortable living and working conditions while minimizing energy consumption and greenhouse gas emissions. To achieve cooling for sustainable development, we need to adopt energy-efficient cooling systems, green buildings, promote education and a big but not often mentioned topic of improving cold storage supply chains. With these steps, we can achieve sustainable cooling and contribute to modifying the effects of climate change and starvation.
